Created attachment 171848 [details] Screenshot with system info, firefox, and the power menu showing. *** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY See attached for full system info, but to add some more info, I have both the standard 6-cell battery (about 57ish watthours new) and a 9-cell slice battery (about 94ish watthours new). They should be counted as batteries 1 and 2, but whenever I detach the slice battery, or put the system in sleep mode, both numbers will count up inexplicably. I'm now up to 6 and 7 just from testing that. STEPS TO REPRODUCE 1. Acquire dual battery laptop 2. Remove battery 3. Reattach battery OBSERVED RESULT What used to be battery 1 and 2, have now become 2 and 3, respectively. EXPECTED RESULT They should remain as 1 and 2, like in Windows.
